WARNING LIGHTS AND CHIMES
Check engine
Your vehicle is equipped with a
computer that monitors the engine's
emission control system. This
system is commonly known as the
On Board Diagnostics System (OBD
II). This OBD II system protects the environment by ensuring that your
vehicle continues to meet government emission standards. The OBD II
system also assists the service technician in properly servicing your
vehicle.
TheCheck Engineindicator light illuminates when the ignition is first
turned to the ON position to check the bulb. If it comes on after the
engine is started, one of the engine's emission control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.
What you should do if the check engine light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause yourCheck Enginelight to
illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the fuel.

3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with high quality fuel of the recommended octane and/or properly
installing and securely tightening the gas cap. After three driving cycles
without these or any other temporary malfunctions present, theCheck
Enginelight should turn off. (A driving cycle consists of a cold engine
startup followed by mixed city/highway driving.) No additional vehicle
service is required.
If theCheck Enginelight remains on, have your vehicle serviced at the
first available opportunity.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Check fuel cap
Illuminates when the ignition is
turned to the ON position. It will
also illuminate when the fuel filler
cap is not installed properly. Check
the fuel filler cap for proper installation.
For more information, refer toFuel filler capin theMaintenance and
carechapter.
Air bag readiness
Momentarily illuminates when the
ignition is turned ON. If the light
fails to illuminate, continues to flash
or remains on, have the system
serviced immediately.

High beams
Illuminates when the high beam
headlamps are turned on.
Anti-theft system (if equipped)
Refer toSecuriLockypassive
anti-theft systemin theControls
and featureschapter.
Charging system
Illuminates when the ignition is
turned to the ON position and the
engine is off. The light also
illuminates when the battery is not
charging properly, requiring
electrical system service.
Check gage
Illuminates when the engine coolant
temperature is high, the engine oil
pressure is low or the fuel gauge is
at or near empty. The ignition must
be in the ON position for this lamp to illuminate. The lamp will also
illuminate for several seconds after the ignition is turned to the ON
position. Refer toEngine coolant temperature gauge, Engine oil
pressure gaugeorFuel gaugein this chapter for more information.
Four wheel drive low (if equipped)
Momentarily illuminates when the
ignition is turned to the START
position. Illuminates when
four-wheel drive low is engaged. If
the light continues to flash have the system serviced.

Four wheel drive high (if equipped)
Momentarily illuminates when the
ignition is turned to the START

four-wheel drive high is engaged. If
the light continues to flash have the system serviced.
Door ajar
Illuminates when the ignition is in
the ON or START position and any
door is open.
O/D off
Illuminates when the Transmission
Control Switch (TCS), refer to
Overdrive controlin theControls
and Featureschapter, has been
pushed turning the transmission overdrive function OFF. When the light
is on, the transmission does not operate in the overdrive mode, refer to
theDrivingchapter for transmission function and operation.
The light may also flash steadily if a transmission malfunction is
detected. If the light does not come on when the Transmission Control
Switch is depressed or if the light flashes steadily, have your vehicle
serviced as soon as possible, damage to the transmission could occur.
Check air suspension (if equipped)
Illuminates momentarily when the
ignition is turned to the ON position
and the engine is OFF. The light
also illuminates when the air
suspension system requires servicing.
For information, refer toAir suspension systemin theDrivingchapter.

Speedometer
Indicates the current vehicle speed.
Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the area
between the ªHº and ªCº). If it
enters the red section, the engine is
overheating. Stop the vehicle as
soon as safely possible, switch off
the engine immediately and let the
engine cool. Refer toEngine
coolantin theMaintenance and
carechapter.

Battery voltage gauge
This shows the battery voltage when
the ignition is in the ON position. If
the pointer moves and stays outside
the normal operating range (as
indicated), have the vehicle's
electrical system checked as soon as
possible.
Engine oil pressure gauge
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle remains
in the normal range (the area
between the ªLº and ªHº).
If the gauge indicates low pressure,
stop the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level.
Add oil if needed (refer toEngine
oilin theMaintenance and care
chapter). If the oil level is correct, have your vehicle checked at your
dealership or by a qualified technician.
Fuel gauge
Displays approximately how much
fuel is in the fuel tank (when the
key is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion. The ignition
should be in the OFF position while
the vehicle is being refueled. When
the gauge first indicates empty,
there is a small amount of reserve
fuel in the tank. When refueling the
vehicle from empty indication, the
amount of fuel that can be added will be less than the advertised
capacity due to the reserve fuel.

System check
Press the system check control to
display the status of the following
systems:
²engine oil life left
²engine oil level
²voltage level
²engine coolant temperature
²washer fluid level
²fuel level
The engine oil life left has two phases. The first display will indicate the
oil change status (OK, SOON, REQUIRED). The second display will
indicate the percentage of oil life remaining. The display OIL TEMP
SIGNAL ERROR indicates a problem with the system. Following this
display, contact your dealer or qualified service technician for system
maintenance.
Operating the message center during system check
The message center controls can be operated as follows during the
system check sequence:
1. Press the system check controls to advance to the next display.
2. Press the reset control to immediately conclude the system check.
3. Press the range, fuel status or fuel economy control to conclude the
system check and display the requested feature.
4. Press the metric/English control to conclude the system check and
change the previous display to the new mode.
5. Press the oil change reset control to conclude the system check and
begin the oil change reset procedure.
An oil change is recommended whenever indicated by the message
center. Use only recommended engine oils.
The message center will tell you the percent of oil life left during system
check. This percentage is based on your driving history and the time
since your last oil change. In order to ensure accurate oil life left
indications, you should only perform the following procedure after you
have the oil changed.
